“Witnesses stated the suspect vehicle was seen swerving into the oncoming lane, then collided with a truck and came to rest next to a hydro pole,” said Const. Gary O’Brien, Nanaimo RCMP spokesman, in an e-mail.

B.C. Ambulance, Nanaimo Fire Rescue and RCMP responded.

The driver, a 39-year-old Nanaimo man, was unconscious and treated at the scene by paramedics who used Narcan to revive him.

“The driver was taken to local hospital,” O’Brien said. “Impaired driving by drugs investigation is underway.”
